MultiScanner 740 Electronic Wall Scanner with Built-In Erasable Wall Marker

Me ha ayudado para encontrar metales y cosas electricas. cumple su funcion. Es lo mas basico de lo mas basico,

Pricey but works - used on stud walls to find stud to fix a chest of drawers to the wall as we have young children. I had a strong magnet which i was able to use to find the nails in the studs but this was just a little easier and unlike the previous one I had - it gives the same answer every time. Read the instruction re calibration before us and away you go.

Finding wooden studs in ceiling and walls

I would grade this new Zircon stud finder at 3.5 for reasons given below in the con section.This is the second Zircon stud finder I have. The first [older] was bought over the last 10 years and is simply labeled as STUDSENSOR. This new product is just as inconsistent as the first. The older model has a vertical set of red LEDs. As you transverse the stud, the LEDs light from bottom one at a time to the top light. The center of the stud is implied by the top light lit. As you pass the stud, the LEDs turn off in descending order from top to bottom. One's job is to judge where center is by picking a point in the middle of the upward and declining LEDs.This new model is more definitive about where it thinks the stud-center is located in scanning from left to right by beeps and when an upward pointing LED light on the wall appears, a 3 bar strength indicator is lit, and the middle of a 4 segmented bar is shown. At times it stays on until it decides to turn it off (perhaps by seeing the right edge being detected. (Scanning from right to left shows the bar, but no beep until the center is detected). As you move along you must watch the segmented, black horizontal bar carefully as it will be the 1st indication of the end of the stud (I believe the second is indicated when the strength indicator bars disappear).Pros:Center indicator of stud is usually right on.The segmented bar helps to understand the studs width if that is important to you.Cons:Inconsistent results when scanning in reverse. The user interface changes slightly.The screen is too small for the amount of information being presented; I surmise to conserve battery power.Bar segments hard to see and questionable in value.The signal strength is too weak to detect foil wrapped Zip power line. In my experience, contractors will use large hole cutters to run power cable. The cable could be resting anywhere in the space of the hole. In my application, I'm wanting the maximum depth screw into the edge of a 3/4. The sensor's limitation (as is also with other sensors on the market) is detection up to 1.5". I have 5/8 drywall. That leaves a screw anchor of only 1 inch. This unit will not see most of the power lines. Nor will it see any low voltage cable used for intranets, appliances, etc. [In some counties, the code requires the contractor to nail across the stud a steel plate to avoid drilling into wiring.]Battery cover is a bit difficult to lock in - wires attached to battery post are in the way.Battery life is not specified.The higher up the wall you use this product, it's more important to have a straight on view of the screen, and the use of a 3rd arm for balance and the use of a marking instrument.I did not validate the detection of non-ferrous metal.

The best scanner I’ve found that does what it’s supposed to do.
